Dough

• 2 tbsp active dry yeast
• 4 cups all-purpose flour
• 1 tsp salt
• ⅓ cup white sugar
• ⅓ cup softened butter
• 1 cup lukewarm milk
• 1 egg yolk
• 1 egg
• 1 package vanilla sugar or 1 tbsp vanilla extract

Filling

• 1 ¼ cups plum jam
• 1 tbsp rum (optional)

Topping

• ¾ cup ground poppy seeds
• Powdered sugar
• ½ cup melted butter
• Vanilla custard sauce

Dough

1. Mix the flour, salt, vanilla, eggs, and sugar in a bowl.
2. In another bowl, mix the lukewarm milk with the yeast, and stir until all of the yeast has dissolved.
3. Pour the liquid mixture into the flour, and knead everything together with the softened butter. If the dough is too sticky, add more flour.
4. Cover the dough and leave it to rise for one hour until it has doubled its size.

Shaping

5. Divide the dough into 8 pieces. Pat them flat and round on a board until they are about 4 inches in diameter.
6. Fill each of the pieces of dough with a tablespoon of the plum jam, and carefully form round dumplings. Make sure that the seam is completely closed.
7. Place the dumplings on a board with a dishtowel covering them, and let them rest for 10 minutes.

Cooking

8. Boil salted water in a large pot.
9. Add the dumplings to the pot. Depending on the size of the pot, only add about 4 at a time so they have space to rise.
10. Let them simmer for 20 minutes with the lid on. Do not take the lid off, as the dumplings will not rise properly.
11. When finished, remove the dumplings, and place them in a bowl.
12. Top the dumplings with poppy seeds and powdered sugar. Pour butter or vanilla sauce over the top.
13. Serve right away. Enjoy the delicious dumplings!
